Leybold HV Standard – Trivac® B Series

Features:

  • Direct-drive
  • Small footprint, end-mounted sight glass, end-mounted controls, and inlet/outlet ports that can be positioned either vertically or horizontally

About Its Design:

  • Incorporates forced-feed oil lubrication and all solvent-resistant seals and gaskets
  • Oil-casing, coupling housing, inlet, and exhaust ports are made of aluminum (not made of corrosion-prone nonferrous heavy metals)
  • Running these pumps continuously in rough vacuum requires a Mist Eliminator with oil return.

Applications:

  • Chemistry / Pharmaceutical
  • Vacuum Coating
  • Lamps / Tubes Mfg.
  • Freeze Drying
  • Cooling and Air Conditioning
  • Vacuum Degasing
  • Metallurgy / Furnaces
  • Leak Detection
  • Backing Pump for High Vacuum Pump
